Thanks!  If you could provide me with a patch that works around the issue in the local theories, that could help me investigate the remaining problem.

The looping print_locale hints at an issue in dependency resolution itself.  I don't know whether the example has ever worked (probably it has not), but I find it useful enough to pursue.
